When I try to set the Skin to Material I obtain the following Error:

The problem happens when the ButtonType="ImageButton" is set with the Material skin:

<telerik:GridEditCommandColumn ButtonType="ImageButton" HeaderStyle-Width="20px" >
</telerik:GridEditCommandColumn>
<telerik:GridButtonColumn ButtonType="ImageButton" UniqueName="DeleteColumn" Text="Elimina" HeaderStyle-Width="20px" CommandName="Delete" ConfirmText="Procedere con la cancellazione del Cimitero?"></telerik:GridButtonColumn>

Release 2024 Q2

Found an additional issue when implementing this on a project:

When aria-enabled=true and we follow their instructions if we have a gridnumericcolumn in the grid, then we get a finding that "Elements must only use supported ARIA attributes" because To solve this problem, you need to fix the following:

 

ASPX

                <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" AllowFilteringByColumn="true" OnNeedDataSource="RadGrid1_NeedDataSource" EnableAriaSupport="true">
                    <ClientSettings>
                        <ClientEvents OnGridCreated="OnGridCreated" />
                    </ClientSettings>
                    <MasterTableView>
                        <Columns>
                            <telerik:GridBoundColumn DataField="ID" HeaderText="ID" UniqueName="ID" />
                            <telerik:GridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name" />
                            <telerik:GridCheckBoxColumn DataField="IsActive" HeaderText="Active" UniqueName="IsActive" />
                            <telerik:GridNumericColumn DataField="Score" HeaderText="Score" UniqueName="Score" DataType="System.Int32" DataFormatString="{0:N0}" />
                        </Columns>
                    </MasterTableView>
                </telerik:RadGrid>

ASPX.CS

    protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        // Creating a dummy data source
        var data = new List<DummyData>
        {
            new DummyData { ID = 1, Name = "John Doe", IsActive = true, Score = 88 },
            new DummyData { ID = 2, Name = "Jane Doe", IsActive = false, Score = 92 }
        };

        RadGrid1.DataSource = data;
    }

    public class DummyData
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public bool IsActive { get; set; }
        public int Score { get; set; }    
    }

When I want to clear a class in the RadEditor the class is cleared in the hyperlink manager, but not in the area in the footer of the RadEditor.

If 'clear class' is selected nothing happens.

This does not happen with MetroTouch, Silk or Default skin. How do I replicate the same behavior with Metro skin?

We are trying to make our website accessible using Wave and one thing we are struggling with is TreeViews with checkboxes enabled. Sometimes the checkbox is rendered as a span element and sometimes as an input element. In the second case Wave is recognizing an error for each node as the input element is not associated with its neighbouring text. You can see this on your own website: https://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/checkboxes/defaultcs.aspx. For the server side tree the checkboxes are rendered as inputs and there is no label associated with it.

This behaviour doesn't change when I set EnableAriaSupport="true".

When search dropdown is open in MultiColumnComboBox and you scroll the page (e.g. by mouse wheel) the dropdown is immediately closed which is quite inconvenient.

Both Combobox and DropDownList keep the dropdown opened when you are scrolling the page.

Could you fix it?
Any temp workaround?

The contrast between the colors for the background and the text in the Tooltip of the Chart series is very low (dark background and black text). https://www.screencast.com/t/fhx6937j

The problem is most obvious in the Outlook, Simple, Web20 and Sunset skins. 

Workaround would be  setting the Color property for the ToolTipAppearance to White

In R3 2016 SP1 when a RadEditor with RenderMode=Classic is disposed and RadScriptManager is used, a JavaScript error is thrown:
IE:  Object doesn't support property or method 'dispose'
Chrome: Uncaught TypeError: this._contextMenuFunctionality.dispose is not a function

FIXED in R3 2016 SP2 (2016.3.1027)

There are three workarounds:
- Set EnableScriptCombine to false for the RadScriptManager (not applicable when CDN is used)
- OR set RenderMode=Lightweight for the RadEditor (you can do this in the web.config for all control instance in the web app if they do not define the Classic mode exiplicitly)
- OR add the following function override at the end of your page:

			<telerik:RadScriptManager ID="RadScriptManager1" runat="server" >
			</telerik:RadScriptManager>

			<%-- WORKAROUND 1: SET EnableScriptCombine="false" TO RADSCRIPTMANAGER--%>

			<asp:Button ID="Button1" Text="click to postback and break the editor" runat="server" />

			<telerik:RadEditor ID="txtInstructions" runat="server">
			</telerik:RadEditor>

			<%-- WORKAROUND 2: SET RenderMode="Lightweight" TO RADEDITOR--%>


			<%--WORKAROUND 3: ADD THE FOLLOWING SCRIPT TO THE END OF THE FORM--%>
			<script>

				Telerik.Web.UI.Editor.DefaultToolAdapter.prototype.dispose = function ()
				{
					delete this._fakeToolbarParentCreated;
					var toolbars = this._getToolBarElements();
					if (toolbars) {
						for (var i = 0; i < toolbars.length; i++) {
							$clearHandlers(toolbars[i]);
						}
					}
					this._tools = [];
					this._disposeToolbarModeHandlers();
					var wnd = this._toolbarHolder;

					var contextMenuFunctionality = this._contextMenuFunctionality;

The menu commands for Telerik projects sometimes are not visible. The reason why is that the visibility state of the commands is evaluated asynchronously. Depending on the time it takes to evaluate the command state, sometimes the commands are not available when they are queried for the first time.

NOTE: It can be observed in all Telerik products.

When the AriaSupport for the Grid is turned on, an aria-label is added to each column header automatically using the UniqueName of the column. The problem is - UniqueName doesn't support empty spaces - all "labels" must be single words or use Underscores - and the screen readers say "underscore."

So my column of "call_date" results in "Call underscore Date" - which is not useful for visually impaired people.

When the grid has a horizontal scroll bar displayed, we can't scroll the table horizontally using keyboard only.  If testing using the Siteimprove Accessibility Checker, we will get the issue "Scrollable element is not keyboard accessible".

The reason is that when the RadGrid is rendered, the horizontal scroll bar is render as a separate <div> out of the data table, and the horizontal scroll bar doesn’t have a tabindex, so there’s no way to put focus on it using keyboard.  Can you add tabindex="0" to the horizontal scroll bar?

1.       Visit the RadEditor demo at https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx (I used Google Chrome.)

2.       In the HTML view, replace the entire demo text with

This <strong>strange</strong> thing

3.       In the Design view, place the cursor at the very end of the line, and press Shift+Left repeatedly.

a.       At first it will highlight the final letter correctly.

b.      Then it will UNHIGHLIGHT the final letter!

c.       Then it will begin highlight more letters again starting from the letter BEFORE the final letter.

d.      Then, after highlighting the “e” in strange, it will being UNHIGHLIGHTING starting from the righthand side of the selection!

e.      Then it will highlight left as far as the “s”.

f.        Then it will start UNHIGHLIGHTING from the right again!

g.       Then highlighting the space to the left

h.      Then UNHIGHLIGHTING the space to the left!

i.         Then highlighting to the left as far as the beginning of the line

j.        Then UNHIGHLIGHTING from the right side of the selection!

Pressing Shift+Left and Shift+Right should always modify only one end of the selection, and the other end should always remain where the selection was started. This is how Windows Notepad and virtually all other applications behave.

Steps to reproduce the text highlighting issue:

  1. Go to https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
  2. Delete the content and write a single line
  3. Use the mouse to highlight a portion of text starting at the end (right side) of the text and dragging toward the beginning (left side).
  4. Stop about halfway to the beginning of the text.
  5. Now, while the text is still highlighted, press shift and left arrow to continue selecting. This will work for some time until the highlight gets near the beginning, then, the highlight will start moving from the right side.

When assigning multiple resources and percentages, the first item in list always goes back to 100%.

It saves back to UI correctly but as soon as you leave or refresh page it goes back to 100% on first item and that's what's saved in database.

The online demo has the same code but demo doesn't save at all to test.

See attached screen shots.

I want to be able to let a user choose "Landlords", "Tenants", "Owners" and search for a name. The data for the search box comes from different tables.

<asp:SqlDataSource ID="SqlDataSourceTenants" runat="server"

                           ConnectionString="<%$ ConnectionStrings:ProjectConnectionString %>"
                           SelectCommand="SELECT Id,TenantEntityName as EntityName FROM TenantEntities"></asp:SqlDataSource>
        <asp:SqlDataSource ID="SqlDataSourceLandlords" runat="server"
                           ConnectionString="<%$ ConnectionStrings:ProjectConnectionString %>"
                           SelectCommand="SELECT Id, LandlordEntityName as EntityName FROM LandlordEntities"></asp:SqlDataSource>
        <asp:SqlDataSource ID="SqlDataSourceOwners" runat="server"
                           ConnectionString="<%$ ConnectionStrings:ProjectConnectionString %>"
                           SelectCommand="SELECT Id,OwnerEntityName As EntityName FROM OwnerEntities"></asp:SqlDataSource> 

I would like to set the DatasourceId on the RadSearchBox to one of the above when the SearchContext changes. I have worked out how to get the selected searchcontext text via an Ajax Request.

     function OnClientLoad(sender, args) {
                    var context = sender.get_searchContext();
                    var $ = $telerik.$;
                    $(context).on({
                        "selectedIndexChanged": function (event) {
                            var searchbox = $find("<%=RadSearchBox1.ClientID%>");

                // this is the search context dropdown selectedIndexChanged event handler 
                            var ajaxManager = $find("<%=RadAjaxManager1.ClientID%>");
                            ajaxManager.ajaxRequest(context.get_selectedItem().get_text());
            }
        });
                }

 

I cannot work out how to change the datasource at runtime (I get datasource not found when I run the following code).

    Protected Sub RadAjaxManager1_OnAjaxRequest(sender As Object, e As AjaxRequestEventArgs)
        if not isnothing(radsearchbox1.datasource)
            select Case e.Argument
                Case "Tenants"
                    RadSearchBox1.DataSource = sqldatasourcetenants
                    RadSearchBox1.databind
                Case "Landlords"
                    RadSearchBox1.DataSource = sqldatasourcelandlords
                    RadSearchBox1.databind
                Case "Owners"
                    RadSearchBox1.DataSource = sqldatasourceowners
                    RadSearchBox1.databind
            End Select
        End If
    End Sub

In the OnSearch Event I just need to get the type of entity (which I could get from checking the Id of the bound datasource) and the Id of the entity:

Protected Sub RadSearchBox1_OnSearch(sender As Object, e As SearchBoxEventArgs)
        If e.DataItem IsNot Nothing Then
            Dim dataItem = DirectCast(e.DataItem, Dictionary(Of String, Object))
            Dim thisId As String = dataItem("Id").ToString()
            Dim thisEntityName As String = dataItem("EntityName").ToString()
            ' Lookup in database and redirect to the relevant data view / edit page
        End If
    End Sub

 

Surely this is a common request and deserves consideration?
